Since the last time I had to update my lists for a new MAME was around 0.179, I have started fresh only to find that the tools I used, like ROMlister and Lightspeed MAMELister are no longer working very well due to the MESS integration "mess" that resulted over time (as I expected), and due to other changes that have been made to the ini/xml/dat formats the tools relied upon...

In trying to get my set down to all the playable (even if slightly flawed) ROMs without completely broken or unplayable (i.e. Mechanical/Console/Computer/Calculator) ROMs, I find I can't trust that the old tools are giving me exactly what I'm trying to achieve. So I thought I'd ask what tools and methods people are using to make their lists/pare down their sets in this modern era?
